Lorenza Guereca doesn’t often let other people see what a challenge living with cancer has been.

She said strong faith keeps her positive after years of treatments. Lorenza, who lives with her husband and daughter in Lafayette, In., said she doesn’t dwell on her illness and makes the effort to maintain an optimistic attitude despite multiple diagnoses, hair loss, and hospital visits.

“You always see me with a smile,” she said. “I don’t think people realize how stressful it is.”
